I have been using them on my mountain bike for the past summer. They are not the lightest on earth, maybe the lightest steel rotors on earth, but certainly scrub alum are lighter. I love how light they are and they work very well.

It is perfectly normal for brand new rotors to not stop as well as used ones, simply because they still have the factory glaze on them. Whenever I get new rotors, I always make a point of sterilizing them with alcohol and then sintering them. That should help to clean them off a bit. Just keep on riding yours though. With time, the stopping will get more powerful.

You need to bed any new disc/pad combo in, braking is actually pad against pad material deposited as a (very) thin layer on the disc, Shimano gives a simple procedure for this involving 20 'stops' at 'moderate' braking from about 15mph to not quite a stop - simples.

Rear rotor is just perfect.But the front doesn't brake as hard as the original Shimano's (BR-M446) do.If I lean to the right on the bike, I can hear one of the pads grinding against the disc.When straight on the bike or leaning to the left there's no problem.

Sound familiar to someone?

Will change front and rear tomorrow and see if something changes.

Is the front skewer tightened adequately? This could be the issue. The caliper may not be completely centered over the rotor too. They caliper may be sitting too far outboard which could be explaining the rubbing.

The skewers are the original Shimanos.Never had an issue with the original rotors. So can't imagine that being the problem, but I will try giving them another turn.

For the rotors I was stupid enough not to clean them First time I've replaced rotors, so apperently I have a lot to learn.Will try to get the top layer off from the pads. Or just buy a new set of pads.
